NOISE BARRIERS:
To reduce the harmful effects of noise, we offer acoustic panels and VELOX walls that, when combined, offer excellent sound proofing and air-curtains. Simple installation allows versatile use, regardless of location, terrain topography or underlying bedrock.

Acoustic panels and VELOX walls create optimum protection from environmental noise and contribute significantly to improving living conditions. Treat yourself to a quieter environment!

Some of the advantages of VELOX noise barriers are:

  • High sound absorption capability
  • High capacity air insulation
  • Simplicity and speed of assembly regardless of the variety of the terrain
  • High durability and resistance to weathering, water, salt, frost and rot
  • Easy replacement of damaged parts and panels
  • Variety of coloured paint or colour patterns
  • Creation of plastic shapes and forms with regard to the character of the landscape
  • Wide application in the area of road and rail routes in residential and industrial zones

VELOX noise boards are made from a mixture of wood chips, cement and fibreglass. It's properties will resist water, salt, frost, rot and mechanical damage. The porosity of the surface ensures excellent damping and noise absorption.

VELOX boards have the necessary rigidity, whilst it is also self-supporting and is used for cladding VELOX panels. The boards can be easily painted and sprayed according to customer requirements.

  • Made from a mixture of wood chips, cement and fibreglass

  • Has the necessary rigidity and load-bearing properties
  • High density for absorbing noise
  • Resistant to weathering, water, salt, frost and rot
  • Can be used for VELOX cladding boards and separately as a fence system

Acoustic panels are made up of a wooden frame and VELOX boards. The acoustic panel frame is assembled from wooden beams, 120 x 80 mm and 100 x 30 mm planks, with protection against rot and mildew Wolmanitem QX-10 with long-term efficiency. The supporting frame is fixed with plated screws and nails.

VELOX boards are adjusted where necessary, and cut according to the architectural design. According to the requirements of the project, it is possible for high sound absorption using the VELOX panels on both sides. Panels can be stacked to create a desired height of the wall.

A noise protection wall (referred to as PHS) is formed by individual soundproof panels (PHP). When building noise barriers, profiled absorbent VELOX plates are used measuring 2000 x 500 mm. This format is crucial to set acoustic panels in various categories.

Category acoustic panels

1) Basic - not necessary to adjust the dimensions of the panels 
2) Modular - not necessary to adjust the dimensions of the panels 
3) Special - the production is necessary to adjust the dimensions of the cutting boards

Dimensions of acoustic panels

Basic dimensions PHP 4000 x 2000 mm. 
When the PHS height is greater than 2500 mm, it is necessary to combine multiple PHP, of differing heights, to each other to form the desired height.
Maximum size of one PHP is 5000 x 2500 mm.

Tolerance in dimensions of PHP:

  • Length ± 5 mm
  • Height ± 5 mm
  • Width ± 5 mm

In the case of installation in profiles HEA / HEB 160 PHP dimension is given by the size of the absorption area profiled
absorbent panels VELOX. 
Duration PHP = sum of the lengths of the boards horizontally on one piece of PHP. 
PHP height = sum of the lengths of the boards vertically on one piece PHP .

For installation in concrete columns is determined by the length dimension PHP wooden frame and height absorbing profiled absorbent panels VELOX. 
acoustic panel length = length of the wooden frame 
height acoustic panel = sum of the lengths of the boards vertically on one piece of PHP.

Basic acoustic panels

Dimensions are given multiple of acoustic panels VELOX without modification cutting.

Standard size of PHP:

Designation (type) PHP Length Height

Modular acoustic panels

Dimensions of modular PHP are all multiples of VELOX acoustic panels without any modification.

Plate height is 2000 mm

Atypical acoustic panels

Dimensions of atypical acoustic panels are not whole multiples of the size of VELOX noise boards. In the production it is necessary to modify the dimensions of the panel.

Atypical acoustic panels are divided into groups:

  • By length
    • below 2500 mm (outside multiples slab width 500 mm)
    • 2510 - 5000 mm (outside multiples of slab width 500 mm)
  • According to height
    • to 1500 mm
    • 1510 - 2200 mm
    • 2210 - 2500 mm

VELOX noise barriers are used to dampen noise such as in tunnels, under bridges or in places that do not allow the use of classical acoustic panels, such as retaining walls.

How does it work?

1) Anchoring to concrete walls

VELOX noise panels are hung on the wall using the concrete facade anchor system SPIDI, which reinforces the concrete wall's SPIDI anchors. The board itself is anchored to the horizontal position of the beam anchor system made of high-strength aluminum, due to their high weather resistance and durability.

Before starting, work must be done to measure out any unevenness. Subsequently begin by mounting the SPIDI max console AlZn, so supporting L-profil 45/55 mm formed continuous plane. Supporting L-profiles to SPIDI max consoles gaining hold self-tapping screws SBS 4.8 x 16 mm. SPIDI anchors are attached to the concrete wall in 2 pieces per meter at centers 1200 mm. In the case of unevenness to use plastic shims. On the L-profiles with VELOX acoustic panels fixed screws of sufficient length. After complete assembly, execute coating the same way as noise barriers.

2) Anchoring the steel

Construction using concrete solution suggests architecture based on calculations. They must determine the dimension of vertical and horizontal structures due to their load boards. Example anchorage for steel construction (noise cooling units): The vertical beams I200 1 are fixed horizontal flank U80/140/80 thickness. 4 mm 2 using anchors and screws with the mother and washer M12 3rd Number of spandrel beams at 2 m height is 3 pieces - bottom, middle and top of the plate - fourth condition for the smooth anchor plates is offset vertical and horizontal structures in one plane, called a plane. T tile is mounted on each side runner 3 self-tapping screws or special bolt-driving nails onto steel structures. These can be mounted directly absorbing the VELOX plate or the first WSD35 plate as a base for absorbing plates of different profiles. Steel structures may enclose one side or both sides (see picture). Finishing boards as PHP.
